Well, the dust is toxic, for one. It is a very oily wood, making glue joints difficult. It also can gum up tools and sandpaper, and it can be difficult to finish because of the high oil content. I have to wonder how other builders deal with these problems.
I had dreams of having a cocobolo-topped Dingwall someday....alas, looks like that won't happen.

Fanned fret Alembic? Maybe.
